The 1937 120 water pumps are different from the 1938. The '37 has a string-type packing, a packing nut, and plain bushings. The 1938 pumps have ball bearings and a mechanical seal with no packing nut. The two pumps are also different where they attach to the block, and the pump to block gaskets are different. I think the '38 pumps have a larger shaft, too, so the fan and pulley would be different. An NOS block may have had the original engine number stamped on it, but any casting dates should indicate if it is a later block.
